GAS-BURNER. v

Specification of Letters Patent.

Patented Aug. 4, 1914.

Appiicanon inea may er, 1914. serial No. weon To all whom it may concern 1 Be it known that I, JOHN W .,HiGoINs, a citizen of the United States, residing at Jackson, in the county of Jackson and State of Ohio, have invented a new and useful Gas-Burner, of which the following is a specification.

The present invention appertains to gas burners, and aims to provide a novel and improved gas burner applicable to the tire box of a furnace, boiler, stove, or the like.

The present invention contemplates the provision of a gas burner comprising a 1 unique assemblagey of componentpar'ts, to

enhance the utility of the device, the present device including' a peculiar arrangementof mixing tubes radiating from a central `supply chamber, in.-4 combination with a hood or dome assembled with the mixing tubes inai novel manner to prevent back firing and to assist in supplying the' air to the mixing tubes.- i

With the foregoing and other objects in view which will appear` as the' 4description proceeds, Vthe inventionl residesinthe combination and arrangement of parts'j and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scopeof .what is claimed without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in 4the accompanyingI drawing, wherein fligurc 1 is a plan View, partly in section, ot the bui-menthe section being taken on the line 1-1 of-Fig. E2. Fig. 2 is a sectional view of the burner, taken on the line 2 2 of l? ig. 1.

The present device embodies a central gas chamber 1, which is preferably in the form of a casting, and which has a lower inlet 2, into which the upper end of the gas supply pipe 3 is threaded or otherwise engaged. The periphery of the chamber 1 is provided with an annular series' of outlet openings or 'apertures et, in which are threaded outlet nipples or nozzles which project radially from the chamber 1.

are equipped at their outer ends with arclr ate cham'beied burner heads 7. The mixing tubes G are preferably integral With the heads 7, and the faces or outerisides of the heads 7 are provided with outlet apertures or orifices 8. The mixing tubes 6 project from the inner sides of the heads 7 intermediate the ends of the heads, and the heads 7, as a whole, are arranged in a circular or annular series` The mixing tubes 6 arc provided adjacent their inncr ends, or adjacent the nipples 5, with air inlets l), and -air valves o1 shutters 1() are rotatably mounted upon' the inner end portions of the mixing tubes 6 to control tho imssagc oi' air through the openings or air inlets 9.

A. hood or dome 11 is disposed over the chamber l, and is of a diameter sufficiently large, in order thatthe rim of the hood or dome may engage the mixing tubes (S beyond the air inlets 9 and air valves or shutters 10.

The rim or periphery of the bell or dome is i y( nd the air inlets i).

In applying the burner Within the lire box of a furnace, boiler, or the like, thechamber 1 is seated upon the grate, and the air sup` ply pipe 3 is passed upwardly through the grate and attached to the chamber 1. The supply pipe 3 may be provided with a suitable controlling valve (not shown), to regulate the flow of gas intothe chamber 1. The burner heads 7 may then be seated upon the grate, and the inner ends of the mixing tubes 6 slipped over the nozzles or nipples 5, in which event the hood or dome 11 may be placed over the chamber 1 and the inner end .portions of the mixing tubes (i. mixing tubes 6 being received by the slots The' 12 of the #dome or hood 11, and the slccvular l9 to prevent back firing. In order that the hood 11 may'assist in holding the mixingr tubes iii-engagement with the nipples it is essential that `the valves or shutters 10 be `frictionally or otherwise held against longitudinal movenunt relative to the mix ing tubes, :is will be obvious. The air is adapted to flow ulnvardly through the grate into the hood or dome 11 and from within the dome or hood 11, the air may enter the air inlets 9 of `the mixing tubes, to commingle with the streams of gas passing into the' mixing tubes from the nipples 5. The

central chamber l permits the gas to be readily supplied to the several nipples and intofthemixing tubes with approximate unifor-mity, and furthermore, the gas will .be

so agitated within the chamber l, to assure of a proper discharge of the` gas through the nipples or nozzles V5 into the mixing tubes'- wherein. the air and gas will be ad I' mixed thoroughly. The mixture will then flow 'into thefburner heads 7 from the. mixing tubes 6," and will be discharged through vrthe apertures S to support the flames. The llames Will be arranged in lan annular series to properly heat the sides of the lire box.

The several parts may be readily assembledand separated,.and the present device is otherwise of advantage. The parts may vbe constructed in various sizes .and propor tions, so asto beapplicable to various furnaces, boilers, stoves, and the'like, and the number of mixing tubes 6 may be' increased or l'diminished according to th`e `circumstances, f

Having thus describedV the invention, what is claimed-as new is :-w t

1. In a gasburner, a chamber, radial mix- 'ing tubes having their inner ends slidably connected .tothe chamber to communicate withv `the interior thereof, a hood disposed over the chamber and having its rim provided with downwardly opening slots engaged over the mixing tubes, the mixing tubes having air inlets within the hood, and

members mounted upon the mixing tubes ples, t-he mixing tubes having air inlets ad.

jacent their inner ends and having burner heads at ltheir outer ends, rotatable controlling valves mounted upon the inner end'portionsof the mixing tubes tocontrol the pasi sage of air through the air inlets, and av hood disposed over lthe said chamber, the rim of the hood having downwardlyopening slots. engaged over the n'nixing tubes, the

hood inclosi'ng the said air inlets and 'valves and cooperating with said valves to assist in holding the mixing tubes in engagement with the nipples.

' In testimony that- I claim `the foregoing as my own, I have hereto aiiixed my signature in the presence of two witnesses.
